This has been shown to happen to NDTs for 2 main reasons. One is a Typo in the view_name.field_name reference and the other reason is a missing fully scoped field reference.
Typo in field name
Error Message:
A LookML model issue occurred.
No such field "produtypo.category" in source explore "order_items"
bucket1/ndttest.view.lkml:4
NDT LookML:
view: ndttest {
derived_table: {
explore_source: order_items {
column: category { field: produtypo.category }
column: count { field: products.count }
Where there is a typo at productypo
and that should be products
Missing Full Scoped Field reference
Error Message:
A LookML model issue occurred.
No such field "category" in source explore "order_items"
bucket1/ndttest.view.lkml:4
NDT LookML:
view: ndttest {
derived_table: {
explore_source: order_items {
column: category { field: category }
column: count { field: products.count }
Where field: category
should be written fully scoped as field: products.category
